- Abstract:
- Chitosan Schiff base derivatives were synthesized by the condensation reaction of chitosan andsalicylaldehyde in an ionic liquid,1-butyl-3-methylimidazolium chloride ( BmimCl). The effect of some reac-tion conditions,such as the molar ratio of free amino group to salicylaldehyde,reaction temperature and reac-tion time on the degree of substitution ( DS) has been investigated.The DS could be reached 29.2% at theoptional condition(0.15 g chitosan dissolved in 10 g BmimCl,the molar ratio of free amine group to salicylal-dehyde of 1:2.5,a reaction temperature of 80 ℃,and reaction time of 2 h). The product was characterizedby Fourier transform infrared ( FTIR ) ,nuclear magnetic resonance ( NMR)，and X-ray diffraction (XRD), respectively. A series of chitosan schiff base derivatives was synthesized under the optimal conditions.
